  Re: wnet use DAO design in u r project?
Answer
# 1		 
Bascially DAO is used in three tier architecture.
Three tire architecture is comprised of the following layers

1.Presentaion layer
2.Business layer 
3.Data Access layer

Data Access layer will have all the code to intercat with 
the data base server.so that when next time the data base 
server is changed there is no need to chane in the present 
and business layers.
